Abstract

Saphenous vein graft (SVG) aneurysms are a rare but potentially life-threatening complication after coronary artery bypass grafting, with an estimated incidence of 0.07%. Presentations range from incidental imaging findings to severe complications, including rupture, myocardial infarction, or compression of mediastinal structures.
A 65-year-old man with prior 3-vessel coronary artery bypass grafting presented with progressively worsening substernal chest pressure. Coronary angiography and computed tomography angiography identified a 71 × 45-mm saccular pseudoaneurysm of the SVG. Following heart team discussion, the patient underwent intravascular ultrasound-guided percutaneous coronary intervention with sequential covered stent deployment, resulting in complete exclusion of the pseudoaneurysm.
Optimal management remains uncertain because of limited clinical data. This case emphasizes the feasibility of intravascular ultrasound-guided covered stent placement; to our knowledge, this is the largest reported de novo SVG pseudoaneurysm treated with this approach.
In selected patients, covered stent placement offers a safe, minimally invasive alternative to surgery while preserving graft patency.
